Hafellner
Josef Hafellner (1951– ) is an Austrian mycologist and lichenologist. He was awarded the Acharius Medal in 2016 for his lifetime contributions to lichenology. Before his retirement, he was a professor at the Karl-Franzens-Universität in Graz. Hafellner started developing an interest in lichens while he was a student at this institution, studying under Josef Poelt. He earned a master's degree in 1975 and a PhD in 1978, defending a doctoral thesis about the genus '' Karschia''. In 2003, Hafellner received his habilitation. By this time, he had studied with French lichenologist André Bellemère (1927–2014) at Saint-Cloud, where he learned techniques of transmission electron microscopy and how their application in studying asci could be used in lichen systematics. His 1984 work ''Studien in Richtung einer natürlicheren Gliederung der Sammelfamilien Lecanoraceae und Lecideaceae'' has been described as "probably the single most influential publication in lichen systematics in ...

Hafellnera
''Schaereria'' is a genus of lichen-forming fungi. It is the sole genus in the family Schaereriaceae, which itself is the only family in the Schaereriales, an order in the subclass Ostropomycetidae of the class Lecanoromycetes. Taxonomy The genus name of ''Schaereria'' is in honour of Ludwig Emanuel Schaerer (1785–1853), who was a Swiss pastor and lichenologist. Genus ''Schaereria'' was circumscribed by German lichenologist Gustav Wilhelm Körber in 1855, with '' Schaereria lugubris'' assigned as the type species. The genus was accepted a few years later by Theodor Magnus Fries. It subsequently fell into disuse as William Nylander placed it in synonymy with ''Lecidea''. Josef Poelt and Antonín Vězda resurrected the genus in 1977, and included '' S. cinereorufa''. ''Schaereria'' is one of several dozen genera whose species were previously included in the large genus ''Lecidea''. However, ''Lecidea'' has a different ascus structure than ''Schaereria''. The family S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acharius Medal
__NOTOC__ The Acharius Medal is awarded by the International Association for Lichenology (IAL) for lifetime achievement in lichenology. The organization resolved at its 1990 meeting that it would simultaneously honor professional achievement and commemorate Erik Acharius (recognized as the "Father of Lichenology") by presenting a medal in his name. The first Acharius Medal was made in 1846 by the Royal Swedish Mint for the Royal Swedish Academy of Sciences, although the original purpose for that medal is not known. Because the Swedish Mint still had the dies for the original medal, the IAL arranged for new medals to be made. The first of the new medals were awarded in that same year (1992) at the association's congress in Båstad, Sweden. The medal The medal is silver, with Acharius' profile on one side and the recipient's name on the other. Recipients Source: 2021: * Per Magnus Jørgensen * James D.

Josef Poelt
Josef Poelt was a botanist, bryologist and lichenologist. He held the chair in Systematic Botany and Plant Geography at the Free University of Berlin (1965 - 1972) and then was head of the Botanical Institute and Botanical Garden of Graz University, Austria (1972 - 1990). Early life and education Josef Poelt was born in 1925 in the village of Pöcking in Bavaria, Germany, where his parents ran a guest house. He began to study botany at the Ludwig Maximilian University of Munich but due to the start of the Second World War he joined the German army and was assigned to an intelligence unit in Russia. After illness and time as a prisoner of war of the British, he returned to university study in 1946 and graduated with a bachelor's degree in natural sciences in 1950. Poelt was influenced by a botanist, H. Paul, to study non-flowering plants. He made use of the lichen herbarium at the university's botanic garden which contained nineteenth century specimens collected by Ferdinand Arno ...

Karl-Franzens-Universität
The University of Graz (german: link=no, Karl-Franzens-Universität Graz, ), located in Graz, Austria, is the largest and oldest university in Styria, as well as the second-largest and second-oldest university in Austria. History The university was founded in 1585 by Archduke Charles II of Austria. The bull of 1 January 1586, published on 15 April 1586, was approved by Pope Sixtus V. For most of its existence it was controlled by the Catholic Church, and was closed in 1782 by Emperor Joseph II in an attempt to gain state control over educational institutions. Joseph II transformed it into a ''lyceum'', where civil servants and medical personnel were trained. In 1827 it was re-instituted as a university by Emperor Francis I, thus gaining the name ''Karl-Franzens-Universität'', meaning ''Charles Francis University''. Over 30,000 students are currently enrolled at the university. Academics The university is divided into six faculties, the two largest are the Faculty of ...

Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolu ...

Taxon
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first mad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientific Publication
: ''For a broader class of literature, see Academic publishing.'' Scientific literature comprises scholarly publications that report original empirical and theoretical work in the natural and social sciences. Within an academic field, scientific literature is often referred to as the literature. Academic publishing is the process of contributing the results of one's research into the literature, which often requires a peer-review process. Original scientific research published for the first time in scientific journals is called the primary literature. Patents and technical reports, for minor research results and engineering and design work (including computer software), can also be considered primary literature. Secondary sources include review articles (which summarize the findings of published studies to highlight advances and new lines of research) and books (for large projects or broad arguments, including compilations of articles). Tertiary sources might include encycl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
